commit e86ef05d84749c5a15d7bcf30f78056ca205489c
Author: Dan Williams <dcbw@redhat.com>
Date: Wed Sep 1 17:08:10 2010 -0500
wifi: ensure Enabled state is preserved regardless of rfkill (bgo #624479)
Previously the "Enable Wireless" state was somewhat tied to rfkill state,
in that when NM started up, rfkill state would take precedence over what
was listed in the state file, and if you rmmodded your wifi driver and
then modprobed it again after disabling wifi from the menu, wifi would
magically become re-enabled becuase rfkill state changed.
Fix that by creating a third wifi/wwan enable state that tracks the
actual user preference instead of just the rfkill state so that when
the user disables wifi it stays disabled, regardless of what happens
with rfkill.
